Indy 10 supports OpenSSL 1.0.2u , which allows for TLS 1.2 connections. 3. Troubleshooting Steps 1 Check Bitrate
This guide will provide a thorough, step-by-step walkthrough to diagnose and resolve the issue, explaining the root cause and exploring your available options.
(or versions up to 0.9.7a). Indy 9 does not support OpenSSL 0.9.8, 1.0.x, 1.1.x, or 3.x. Delphi 7 Indy 9 Could Not Load Ssl Library
Add IdSSLOpenSSL to your uses clause and call the testing function during form creation:
Install the Visual C++ 2008 SP1 Redistributable (x86). Or place msvcr90.dll alongside your EXE (check dependency with dumpbin /dependents libeay32.dll ). Indy 10 supports OpenSSL 1

If you prefer configuring your components dynamically at runtime, use the following code structure to properly handle the SSL IOHandler:
Do not download standard OpenSSL files from modern distributions. You need the archived, customized files specifically compiled for Indy 9. Delphi 7 Indy 9 Could Not Load Ssl Library - Google Groups
The error message is a classic roadblock for developers using Delphi 7 and Indy 9. It occurs when your application tries to initiate a secure connection (like HTTPS or secure SMTP) but cannot find or initialize the required OpenSSL dynamic link libraries (DLLs).
